The amino acid sequence of the first of a family of insect cardioregulatory peptides from the tobacco hawkmoth, Manduca sexta, has been determined using a combination of Edman degradation microsequencing and mass spectroscopy. This peptide contains 9 amino acid residues and an observed mass for the monoisotopic protonated molecule of 956.4 Da. There are two(More)
The primary structure of a novel insect neuropeptide, Cardioacceleratory Peptide 2b (CAP2b), from the tobacco hawkmoth Manduca sexta has been established using a combination of mass spectroscopy, Edman degradation microsequencing, amino acid analysis, and biological assays. The sequence of CAP2b, pyroGlu-Leu-Tyr-Ala-Phe-Pro-Arg-Val-amide, has a molecular(More)
The functional relationship between cardioacceleratory peptide 2 (CAP2) and hindgut activity during wandering behaviour was investigated in fifth-instar larvae of the tobacco hawkmoth Manduca sexta. Inspection of the alimentary canal on the day prior to wandering showed that the gut, in preparation for metamorphosis, was voided of all contents by 18:00 h.(More)
BACKGROUND Peritoneal dialysis (PD)-related infections are the major cause of technique failure. Exit-site infections (ESI) can be prevented by local application of antibiotics. Mupirocin (M) is the most extensively studied drug for this application. Long-term use can result in the development of resistance. Gentamicin (G) is an attractive alternative, with(More)
The effects of different language backgrounds on trail making tasks were examined in this study. The measures adopted were the Color Trails Test (CTT) and the Trail Making Test (TMT), the former being the culturally fair analogue of the latter. Eighty-four right-handed participants belonging to the Chinese-English Bilingual (CEB) and English Monolingual(More)
The objective of this study was to evaluate the therapeutic effectiveness of transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) with dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI). Seventeen patients with histopathologically proven HCC were included in this study. All patients underwent MR examinations(More)
The role of neurally derived peptides affecting insect visceral muscle has been explored by many investigators over the past thirty years (e.g. Raabe, 1982; Miller, 1985; Huddart, 1985). One set of myoactive neuropeptides that have been well characterized physiologically is the cardioacceleratory peptides (CAPs) found in the tobacco hawkmoth Manduca sexta.(More)
This paper describes an investigation of 20 different metasearch engines. Their features were characterised and classiŽed into six distinct categories based on their functionality and use. The most used features and unique features were speciŽed and explained in detail. The Žndings of this study will beneŽt both meta-search-engine developers and ordinary(More)
This paper focuses on the views of twenty-six pre-service and eight in-service English teachers in Hong Kong concerning the information technology courses in their teacher education programmes. The findings of the study show that while both software applications and technological integration in teaching are highlighted in the course outline, the instructor(More)
In this paper we investigate the dynamic multi cast routing problem for single rate loss networks and brie y discuss the dynamic multicast rout ing algorithm called Least Load Multicast Rout ing LLMR We propose a new multicast routing algorithm called Maximum Mean Number of New Calls Accepted Before Blocking Multicast Routing MCBMR which can more accurately(More)
